Number of lines in the data table
section = 5/4
= 1 with remainder 1
= 2 lines
(b-4) Example of calculating the number of lines per
screen
For the ladder shown below, the number of lines in
the screen display section is obtained as follows:
- The valid nets on the display
screen are nets A and B.
- Number of lines in net A
Function instruction section +
data table section = 6 lines
(3+1) (11/6)
- The number of lines in net B is 2.

Example of symptom (a-1)
- The ladder diagram can be edited only when the
”total number of message data steps” parameter of
the DISP instruction (SUB 49) is less than or equal
to 396. This is because when the total number of
steps is 396, the net consists of 70 lines.
